Designed particularly for use on guns prior to bluing, or any metal refinishing job. Removes all grease, traces of buffing compounds, dirt. Operates at 180° F. Is non-caustic, and the heavy-duty jug keeps it ready for the next use. One gallon makes from 10 to 21 gallons of cleaner. Will clean most work in 10 minutes; extra cruddy parts may take up to 15 minutes.
